igraph: decompose.graph: Error: protect(): protection stack overflow - R-help

Tue, Mar 20, 2012 11:20 AM #

I just got this error:

Error: protect(): protection stack overflow
Error: protect(): protection stack overflow

what can I do?
the digraph is, indeed, large (300,000 vertexes), but there are very
many very small components (which I would rather not discard).

PS. the doc for decompose.graph does not say which mode is the default.
